GAGE ROLLER BEARING.

Application filed January 26, 1922. Serial No. 531,905.

To all whomit may concern.

Be it known that We, THEODORE E. BARKER and ALFRED E. ELLEFsnN, itizensof the United States, residing at Denver, in the county of Denver andState of Colorado, have invented certain new and useful Improvements inCage Roller Bearings, of Which the following is a specification.

The present invention has for its object the provision of an exceedinglysimple and yet effective holder for roller bearings.

In the accompanying drawings Figure 1 is a side elevation of thepreterred embodiment of the invent-ion.

Figure 2 is a sectional vieW on the line 22 of Figure 1,

Figure 3 is an end elevation with the retaining ring removed,

Figure 4 is an end elevation of the retaining ring,

Figure 5 is a sectional view on the line 55 of Figure 2,

Figure 6 is a detail sectional view on the line 66' of Figure 4.

In the structure disclosed, a unitary body is employed, consisting of ahead ring '1', from one side of which projects partition Walls 8 havingconcave opposite faces, forming pockets 9. In these pockets are placedthe usual roller bearings 10. In the preferred form of construction thebody is formed from a cylinder, the pockets 9 being drilled out.

The free ends of the partition Walls 8 are provided With recesses 11forming in effect the sections of a circle, as will be clear byreference to Figure 3. A retaining ring '12 is adapted to fit upon thisend of the body, and consists of heads 13 that close the open outer endsof the pockets 9, these heads be ing connected by integral Webs 14. TheWebs 14 as shown particularly in Figure 6 pered or generally dovetailed,and are ot a size to fit in the recesses 11, the narrower sides beingoutermost, The end portions of the partitions 8 on opposite sides of therecesses 11 are then inset as shown in Figure 5, thereby securelyholding the retaining ring in place.

From the foregoing, construction, operation it is thought that the and,many advantages of the herein described invention will be apparent tothose skilled in the art, Without further description, and it will beunderstood that various changes in the size, shape, proportion and minordetails of construction may be resorted to Without departing from thespirit or sacrificing any of the advantages of the invention.

aving thus fully described our invention, What We clai a new, and desireto secure by Letters Patent, is

1. A cage for anti-friction roller bearings comprising a body having aplurality of separating Walls defining a series of open ended pocketsfor the bearing elements, said Walls being connected at one end, and aretaining ring at the free ends of the Walls and having enlarged headsthat substantially close the open ends of the pockets and meansembracing the portions of the ring between the heads for securing saidring to the said walls.

52. A cage for anti-friction rolier bearings comprising a body having aplurality of separating r'talls defining a series of open ended pocketsfor the bearing elements, the free ends of said Walls being recessed,and a retaining devie bridging the open ends of the pockets and havingoutwardly tapered portions in the recesses of the partition Walls, theend portions of said Walls on opposite sides of the recess being upsetover said portions.

3. A cage comprising a single pieced body comprlsing a ring anu aplurality of part1- tion Walls integral therewith and projecting fromone side of said ring, providing a series of open ended pockets for thebearing elements, the free ends of said Walls having recesses, andretaining ring comprising a plurality of closure heads or the open endsof the pockets and tapered portions that are in the recesses of theWalls, said walls being upset over the said portions In testimonywhereof, We affix our signatures in the presence of two Witnesses.
